95 S14 window motor assembly problems

[KWASx408]

I bought this car about 6 months ago with the seller telling me the window motor was bad and needed to be replaced. The car came with an "extra" assembly from a junkyard. So today I finally got the urge to replace it. Pulled door panel and see no assembly inside the door. The window is literally zip tied up inside the door. So now I have no idea how to make sure the assembly mounts correctly and the window closes securely when it's fully rolled up. Any insight will be greatly appreciated.
